Maybe Hufflepuff? vary big close 'family' right... in a world like this they could be like the more 'open' people or something, like 'helping' those close to them in the 'pack' or those friends close to the 'pack'. Gryffindor is for people with spirit/adventurist, Ravenclaw is for wit/inquisitive people, and Slytherin for cunning/manipulative. so I can see MC being a Gryffindor for its loyalty to 'friends' and s*xual 'adventures', or Ravenclaw for the s*xual inquisitive people(maybe known for exploring kinks?), or Hufflepuff for the open s*xual relations or make like 'casual' their default with them having open relations with loyalty being to the s*xual group instead of for the good of the Hufflepuff group(whole), can make their strong sense of justice to be for the 's*xual group' so everyone is treated fair and not bad, patience can be for understanding each other, and hard work could be related to how s*xual stuff boosts your power in some way you haven't shown yet.
